  • Patent number: 9938055
    Abstract: The invention relates to a method for loading and storing a vaccine composition, containing the antigen adsorbed on the aluminum adjuvant which (a) comprises (i) loading the composition into a container; and (ii) closing the container with a device in particular acting as a stopper, the surface of the device getting into contact with the composition being coated with a fluoropolymer such as Teflon™ and/or (b) loading the composition into a container wherein the inner surface of which is coated with polymerized silicone. The use of fluoropolymer or polymerized silicone optimizes the adsorbed antigen stability upon storage. In a particular embodiment, the antigen is the hepatitis B surface antigen and the aluminum adjuvant is aluminum oxy hydroxide.

  • Patent number: 9358294
    Abstract: The subject matter of the invention is a method for preparing a vaccine composition comprising at least aluminum oxyhydroxide (AlOOH), and at least the hepatitis B surface antigen and the Haemophilus influenzae type b antigen. According to the invention, the hepatitis B surface antigen is kept adsorbed on the AlOOH, whereas the Hib antigen is kept nonadsorbed. To this end: the hepatitis B surface antigen is adsorbed onto AlOOH in order to obtain an AlOOH/HBsAg complex, then—said AlOOH/HBsAg complex is mixed with the Hib antigen in the presence of cationic amino acids at a concentration of at least 100 mg/l, and of phosphate ions at a concentration of 35 to 45 mMol/l.
